truck died lots of white smoke

[2500sierra81]

so my truck stalled everyone once in a while, after it idled for some time. i talked to a mechanic that had a similar year and he said that the cause could be the HEI (electornic ignition) distributor module, that it happened to him somtimes too. so i went to kragen yesterday and got myslef a new one, (i checked it would fit my truck, same year for the same engine and everything) and i installed it last night. i then drove it and everyhting worked fine. today i drove it to school no problem, but when i come home, and i'm about to park on my street (its on a hill) then engien dies, and throws out a lot (seriously a ton) of white smoke. Now i can't restart the engine. I personally don't think its related at all to the new distributor module since it ran fine all day. any ideas?

Sounds like an overheat, you run it our of water? Water on the ground?

When was the last time you put gas in it?

 

[2500sierra81]

it had 1/4 tank of gas and full coolant/water. taken it to pennzoil day before. everything normal until when the engine died. engine temp gauge was actually lower than usual temp

Start pulling spark plugs, I'm sure at least one will be wet with coolant. Sounds like blown head gasket/cracked head to me.

I bet its a head gasket too. Start by pulling all the spark plugs and do a compression test on all 8 cylinders.

problem fixed

problem fixed last week. new fuel pump and starter. now my engine is mainly all new. kick paneland or windshiedl still leak with the rain, but its good not to have to worry about it stalling in the middle of traffic

Good to hear you got it fixed dude!

 

[HotRodPC]

Hmmm. That doesn't really explain the white smoke though. Glad it wasn't a head gasket and an easy fix.

Yeah, I don't get the fuel pump causing white smoke. Hopefully someone here can share the connection on that one. Glad you got it back running tho

yeah im not sure about the white smoke. the mechanics had no idea either

I had an old car that would do puffs of white smoke once in a while and found it was a bad modulator valve on the transmission....would blend trans fluid in the exhaust and it looked like a James Bond smoke screen.
